Hatch
Oxygen Not Included Guide

Hatch is a nocturnal animal, which looks like a predator, but is not aggressive. Although, if you attack it, it will start to defend itself. Its body yields one piece of high calorie meat. It lies buried in the ground throughout the entire day, just like a mole (but it will remain active until it finds soft ground to burrow). At night, it comes out from its hiding place and searches for food. If it encounters some resources in its way, it will consume up to 50 kg of the material (up to a maximum of 3 times a night). When it is full, it will leave behind 125kg of coal. If there is only coal along its path, it will also eat it and release the same amount of coal again.
